HP G72 notebook upgrade

This 2 GB DDR2 SO-DIMM is built for HP Compaq G Notebook G72-227Wm and G72-259Wm systems. It fits the 200-pin slot and runs at 800 MHz with CL6 timing. The module targets owners of these specific laptops who need a direct replacement or a single-stick capacity increase.

Single stick simplicity

The package contains one 2 GB stick ranked 2Rx8 with major-brand chips. No heat spreader is fitted and the module operates at the standard 1.8 V unbuffered voltage. This keeps installation straightforward in the tight confines of the supported G72 chassis.

DDR2 platform ceiling

The DDR2 interface and the notebook's two sockets limit total memory to 4 GB on a 32-bit OS or 8 GB on a 64-bit OS. Installing the maximum 4 GB may show only 3.5 GB usable due to system address allocation. Buyers needing more capacity or a newer memory standard cannot use this module.

Questions about this item

Will the 200-pin DDR2 SO-DIMM need replacement if the notebook is upgraded beyond 4 GB using a 32-bit OS or 8 GB with a 64-bit OS?

The module is a single 2 GB stick; the system accepts two sockets for up to 4 GB on 32-bit or 8 GB on 64-bit, so adding a second identical stick expands capacity without replacing this one.

What limits sustained throughput on the PC2-6400 CL6 6-6-6 timing?

The DDR2-800 interface and CL6 latency set the bandwidth ceiling; under continuous load the memory controller reaches its maximum transfer rate before the module itself throttles.

How much heat and power does the 1.8 V unbuffered 2Rx8 stick produce when running all day in a G72 notebook?

At 1.8 V without a heat spreader the module draws modest power and stays cool enough for the notebook's existing cooling; no extra fan noise or temperature spike is expected.
